Hello fruhulda
As the OP seems unable to know what her machine did, the fact that Keynote is in version 5.1.1 on the machine make me think that the updater 9.1 was applied but I hate to work upon guesses.
For sure, a good protocol would be :
download my uninstaller:
For_iWork:iWork '09:uninstall iWork '09.zip
apply it
install iWork '09 version 9.0.3 from the DVD
download and apply the updater 9.1

download and apply the updater dedicated to Keynote to bring it in version 5.1.1
http://support.apple.com/kb/DL1477
After that, it would be good to use MAINTENANCE 1.5.0 available from :
http://www.titanium.free.fr/download.php
or Onyx 2.4.2 from the same Web site.
Apply the features checked in the screenshot posted above
Run also FontBook to check the fonts installed and repair problems if some are striking.
This scheme was described several times but it seems that some users are unable to look in existing threads.
